`A=1/2bh`,b=…………….

A=1/2bh ,h=………………….

Area of a triangle is given by A = 1/2 bh. If b= 12 cm and h=7cm find the area of the triangle.

If A= {1,2,3} and B={1,2} then B is……………..of A.

Which of the above is one to many relation ? If A= {1,2,3},B={a,b,c},f={(1,a),(1,b),(1,c)},g={(1,a),(3,c),(2,b)},h={(1,a),(2,b),(3,a)},q={(1,a),(2,a),(3,b),(1,b),(3,a)} then

a : If 1/((x-2)(x^(2)+1))=A/(x-2)+(Bx+C)/(x^(2)+1) " then "A=1/5, B=-1/5, C=-2/5 . R : 1/((x-a)(x^(2)+b))=1/(a^(2)+b)[1/(x-a)-(x+a)/(x^(2)+b)]

If A=[(1,2,3)],B=[(2),(3),(-1)] then (A+B^(T))^(T)=

If A=[(1,-1),(2,-1)],B=[(x,1),(y,-1)] and (A+B)^(2)=A^(2)+B^(2) then (x,y)=

If A'=[(3,4),(-1,2),(0,1)] and B=[(-1,2,1),(1,2,3)] , then verify that (i) (A+B)' =A'+B', (ii) (A-B)'=A'-B'

S.T |(1,a,a^2),(1,b,b^2),(1,c,c^2)| = (a-b)(b-c)(c-a) .
